我有DJI Tello无人机,我想从中接收视频数据。我可以将PC连接到无人机,并通过UDP连接在端口“ 8889”上通过UDP发送命令,但是我不知道如何使用端口“ 11111”从无人机的摄像头接收视频数据。
我使用无人机与PC之间的UDP连接来命令该端口(端口8889),并且运行良好:我可以发送“命令”,“起飞”或“降落”之类的命令,并且收到“确定”。但是,当我将“ streamon”发送到我的电视时,会收到“ Unknow command”(未知命令),并且端口“ 11111”上没有任何内容。
import socket
import threading
import time
class Tello:
def __init__(self):
self.ip = '192.168.10.1'
self.command_port = 8889
self.address = (self.ip, self.command_port)
self.response = None
self.overtime = 3
self.lock = threading.RLock()
self.video_port = 11111
self.socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
self.video_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
self.socket.bind(('', self.command_port))
# init command and video stream
self.receive_thread = threading.Thread(target = self.receive_response)
self.receive_thread.daemon = True
self.socket.sendto(b'command', self.address)
print('sent: command')
last_send = time.time()
self.receive_thread.start()
while self.response != b'OK':
if time.time() - last_send >= self.overtime:
self.socket.sendto(b'command', self.address)
print('sent: command')
last_send = time.time()
# video stream
self.video_socket.bind(('', self.video_port))
self.receive_video_thread = threading.Thread(target = self.receive_video_data)
self.receive_video_thread.daemon = True
self.receive_video_thread.start()
self.socket.sendto(b'streamon', self.address)
print('sent: streamon')
def receive_response(self):
while True:
with self.lock:
self.response, ip = self.socket.recvfrom(3000)
if self.response:
print(str(self.response))
def receive_video_data(self):
self.video_data = None
while True:
with self.lock:
data, ip = self.video_socket.recvfrom(2048)
if data:
print(str(data))
def send_command(self, command):
self.socket.sendto(command.encode('utf-8'), self.address)
#control command:
def takeoff(self):
self.send_command('takeoff')
def land(self):
self.send_command('land')
drone = Tello()
最佳答案
我得到了答案:Tello的固件未更新,因此无法正常工作。
如果您(像我一样)在发送'Unknow Command!'
后得到'streamon'
:
使用您的Tello应用程序并在设置中更新固件。
